Hiya,
Im new and at the pretty basic stages of cake making, I tend to only do it for my childrens birthdays, and its my daughters coming up and I am going to make her a wizards of waverly place spell book cake, the only problem is im not sure on quantities of ingredients to use and how to really go about it as i only have a 8inch square silicone cake mould.
if anyone could help me that would be great,
Thankyou 
Book cakes are very easy to sculpt/build. You should be able to use the pan you already have. Will the book be open or closed?
ETA: here's a good tutorial on a closed book

Thankyou both for replying
its going to be a closed book, I hunted through my cupboards and found two smaller rectangle tins so i have used them and am going to stack them, now its down to hunting through pictures for inspiration on how to decorate it to make it look as real as possible!
